I don't post this with any sarcasm or to draw any inferences about your intended meaning, but just to bring to your attention that the point you've now raised struck me independently upon reading:

> A successful programmer is not just a programmer, he is also a personal representative, a salesman and a contract negotiator.

It is perfectly well formulated. The notation O(f(n)) denotes a set of functions. The question is asking if the two sets O(2^n) and O(3^n) are the same set.
I feel that this kind of criticism is out of place, since Facebook has been working this way (successfully) for almost a decade without anything like that happening on a great scale.

Yes, mistakes can happen and they do happen everywhere, but Facebooks standards seem quite reasonable to me and they must be, since such mistakes would not be tolerated by its users.

Anyways, I doubt that Facebook ever encouraged its users to upload nude pictures. Whoever does this must be out of his/her mind.
I have a question: These are pretty rudimentary questions and if you have a background in the literature, you could brush up in about an hour or two on most of this stuff (aside from memorizing the catalogue of data structures and algorithms you might find in a text book [which makes me wonder why he's focusing on these questions instead of an understanding of induction, space analysis for an arbitrary data structure, or general Big-O/Big-Omega analysis]), but why don't we actually come across uses for that sort of basic stuff all that often?

I mean, I don't know if what I do is all that specialist, but I spend a lot more time working out far less interesting things about how domain knowledge works than what sort of Data Structure or Algorithm is best for storing it and using it.
This is exactly my use case, and I've written glacier-cli to integrate with git-annex in order to fulfil it.
Hmm, does all this imply that a blue-collar IT-workers' class is rising? When I was working during the summers at construction sites in my youth, I noted that everybody all the time complained about the impractical decisions the engineers and architects had made, and grumbling that they had to be there to fix them.

Would they have been happier if they wouldn't have been needed at all?

(disclaimer: I tend to change my shirt between white-collar and blue-collar [figuratively, of course] where I work)
Hah! Make that 91 things learned.
Multiplication instead of addition in the hash will give you the same problems.

I'm not familiar with Github pages, but it seems one cannot store anything on the server-side, it's just HTML+JS. If nothing is sent to any server, there does not seem anything to authenticate or protect from anyone.

His comment wasn't an ad hominem. An ad hominem would be 'this person isn't smart and wise, so his decision's are wrong'. The poster's comment was of the following implicitt form:

* These sort of packages should be run by people who are smart and wise
* The fact that this happened suggests that this person is not smart and wise
* It is unfortunate that he is running a project used by many people.

It's perfectly valid to criticise a person (or a person's fitness for a responsibility) based on their actions. An ad hominem is the opposite - it is criticising a persons actions or arguments based on who the person is (rather than the actions or arguments themselves).

Violent crime rates are down significantly in the US since 1992 (http://en.wikipedia.org/wiki/Crime_in_the_United_States)

Given the popularity of video games in American life it just seems odd that we haven't seen a massive spike in crime given the number of mass murder simulators we've been exposing our young'uns to since arcades became popular in the late 70's.

That's not to say that immersive violent video games don't have any effect - but given how much young males play video games (they also happen to commit the most crimes http://bjs.ojp.usdoj.gov/content/homicide/ageracesex.cfm ) it seems strange there's no visible uptick - if the sky is falling, wouldn't there be some way to tell?

I think in aggregate the data over a span of 10 years would be much scarier than name,address tel no. etc. at a given point in time, however Spokeo is actually making this point anyway right now - they look like they're collecting exactly the sort of data I'm talking about, if you want to call it 'public records' that's fine - most people aren't thinking through the implications of leaving a public trail like this. Not all the data will be available for everyone, but when the data-mining becomes advanced enough, and if you've left a trail on social media, you're talking about possibilities like:

Your exact coordinates at say 20,000 points in the last 10 years (from pics or posts by you or others)

Your meetings with, relationships with, and messages to friends over that time (again posts by you or others)

Your activity at work/home, when you worked, when you didn't (again posts by you or others)

Your use of alcohol and other drugs (legal or not)

Your opinions on almost every topic (culled from various linked postings via your Facebook ID say)

Your membership of hundreds of websites (again culled from links to Twitter/FB logins say)

NB This doesn't just apply to Facebook but I think it will trigger real hesitations about opening up your data to them or similar sites when this sort of scandal first hits in a big way. It also applies in a smaller way even to forums like this.

Of course if someone can mine your email or your bank accounts (i.e. your gov), they'd hit a similar treasure trove of information, so the change with social media is that a lot of your activity is public or only semi-private (and therefore likely to become public), and innocuous in isolation, but possibly very useful/dangerous in aggregate if you and your friends post enough of it.
Samsung might not have tried to copy the iPhone
I'm 51 and I've been programming since I was 21. I write code every day. I love what I do and I have never been more productive than I am now nor have I ever written better code than I am writing now. I write highly complex multi-threaded algorithmic code that operates on extremely large graphs (up to 3.5 billion nodes). I have no interest in getting into management.

I did get "lucky" in that I was a member of the founding team of a publicly traded company and am now a technical co-founder and chief software architect of an up-and-coming engineering software startup. I've written 3 blog posts in career and, except for LinkedIn, I participate in no social media/networking. I've never posted on StackOverflow. Outside of my niche industry, I'm sure that no one has ever heard of me. And, that's exactly how I like it.

Check your day job's rules on who owns things you work on before anything else happens.
The main reason Fortran is used is that medieval professors can't be bothered to learn C. There are less assumptions about pointers in Fortran - which means it can be parallelised more easily - but you can work round that in C.

Sure, but it's a generally unhelpful question I think. Most people aren't going to stay passionate about the same job, career, wife, husband, problems, solutions, whatever, for 50 years.

There is nothing you can do that will make you remain interested and excited and passionate about something for decades.
Comparing the use of positive and negative words doesn't take sarcasm into account.
It's a perfectly sensible question. Knowing that both O(2^n) and O(3^n) are sets, and using the definition of set equality, it asks whether "f in O(2^n)" implies "f in O(3^n)", and vice versa. Only one of the implications holds...
If you mean G+, of course it's no different. If you mean email, typically only governments and courts can get access to that without hacking. I don't feel it's as insidious as daily public postings.
I guess I'll wait for my grading before saying any more :)
You end up with a self-consistent philosophy

Wow, people's view of Ayn Rand is really getting better :).

but there are plenty of those around.

Plenty of those around? I disagree. Even if you're willing to make liberties for what we count as a philosophical system, there are actually only a few options at most. For example, existentialism, Marxism, Kantianism (not even sure I'd count that), various religions (which are really just a primitive kind of philosophy).

Historically, there are three highly unique philosophical "giants." Basically every other philosopher falls into one of these three camps. They are: Aristotle, Plato, and Kant. Aristotle was the this-worldly, holding that knowledge is induced from reality. Plato was other-worldly, holding that knowledge comes about through revelation from a higher realm. Kant was anti-worldly, holding that actual knowledge is impossible.

Rand is the only modern, system-building philosopher who is heavily Aristotelian. Thus, she deserves a serious look from people who are curious as to whether an objective philosophy is possible.

It's not objectively any better than e.g. modern utilitarianism

Utilitarianism is just an ethical doctrine (not a philosophy). Nit picks aside: there are various justifications for it, all of which fall short, because they tell you to sacrifice yourself.

I've never seen a supporter of this position who thinks that the is-ought gap can be bridged, so as far as I'm aware, in any justification of utilitarianism, ethics is just a game, anyway. So yes, people will say "modern utilitarianism is objectively as good as any solution," since no ethical sytems is any "better" than any other. But what if that's not the case? Common sense and history would suggest that some ethical systems are much better than others.

and the moral positions that result align poorly with most people's moral intuitions.

Given humanity's history, any moral system that aligns well with people's intuitions is probably a bloody and destructive one, and so people should be keeping a lookout for something fundamentally different.

Intuitions are just non-explicit ideas that people have been raised with; they don't count towards establishing truth or goodness.

Specifically make sure you can deliver exactly what these eager beavers are willing to sign up for, and that you can do it on time and within budget. They might've got the wrong idea, your mockups might've been too optimistic in their feature set, etc. Just make sure to re-validate your idea and confirm you are on the same page with these people.

> I haven't looked to see if every question is covered by these, but here's some standard textbooks I like:

The good thing is @cpervica has suggested standard textbooks, as opposed to suggesting obtuse texts unreachable to a beginner.

Algorithms:

I think a beginner might be confused by Sedgewick's terse coding style.

Computer Architecture and Operating Systems:

I haven't read either of the books. I would add http://bcs.wiley.com/he-bcs/Books?action=index&itemId=04... to the list. Like most of the OS books, you won't get a full picture of the OS from this book, but you will know the topics which will help you understand a real OS. Also most of the non-recent book won't cover flat memory model http://en.wikipedia.org/wiki/Flat_memory_model That is not to say knowing about segmentation is going to hurt you.

Mathematics:

I haven't read any of the books. From TOC, the cryptography and the statistics book looks good. I would recommend skipping cryptography maths for starters. If you are a beginner, an application level understanding of cryptography is what you need.

Networking and Systems:

Tanenbaums books loves history and theory. It's a nice book nevertheless. Once you are done with it, you should read Stevens' book on TCP/IP http://www.kohala.com/start/tcpipiv1.html

If you find time, you should read the second volume as well:
http://www.kohala.com/start/tcpipiv2.html

For databases, I read this book:

http://www.amazon.ca/Database-System-Concepts-Abraham-Silber...

This is not a very interesting book, but it does cover the fundamentals very well. You will need a bit of will power to read it.
I think that older successful programmers are essentially life-long students of technology.
TL;DR:
Our society frowns on people who set out to do really good work. You're not supposed to; luck is supposed to descend on you and you do great things by chance.

...There are a whole pail full of opportunities, of which, if you're in this situation, you seize one and you're great over there instead of over here. There is an element of luck, yes and no. Luck favors a prepared mind; luck favors a prepared person. It is not guaranteed; I don't guarantee success as being absolutely certain. I'd say luck changes the odds, but there is some definite control on the part of the individual.

This is a good article, but the title doesn't do it justice.

The point that stuck out for me:

Do you find yourself reading/watching/listening to things that leave you feeling a little smarter than you know you have any right to feel? Malcolm Gladwell, TED, etc? The author calls these "insight porn", and posits that they trigger some of the same pleasure centers as real learning.

That's not necessarily a bad thing, but it isn't a full replacement for the real thing, either.

I've often felt this, and been bothered by it, but haven't figured out an effective filter. Source is a good negative indicator (skip the Gladwell unless I'm feeling like powdered cheese), but there are lots of amateur gladwells out there too.

The real stuff is harder to locate, identify, and digest.

And honestly, sometimes the cheap alternatives have a greater ROI, since the investment is so much lower, and the return isn't quantified objectively.

"Oh...that's because the developer that was pontificating yesterday about how heap operations behave asymptotically forgot to check if the database connection was open before he called the Save method. Apparently, such arcane trivia is beneath him. I can fix it."

False dichotomy. You posit the developer who understands asymptotic notation can't figure out why does the application crash, or how to write to databases. I don't see how understanding asymptotic notation negatively affects someone's programming ability..

why is f(n) equal to O(g(n)).. they could have made up a new symbol to establish such a relationship...

It is an equality relationship why would they need a new symbol?

f(n) = O(g(n)) .. n^2 = O(n^2) and n = O(n^2), so n = n^2 which is not making any sense

You are right it doesn't make any sense. Try n^2 = O(Selection_sort(n)),O(Bubble_sort(n)) = O(Selection_sort(n)), n^2 = O(Bubble_sort(n)). Nice and transitive the way it should be.

I am sure there are good things about EVE that keep players engaged, but the initial experience with the "game" is so terrible as to boggle the mind. It isn't sold as a "social experiment". (Its qualities as a "war simulator" I won't go into -- it's a simulator of its own assumptions, which aren't terribly interesting.)

As an aside:

Way back in the early 80s, I was acquainted with a fellow who ran a worldwide play-by-mail game called "Cluster II", and a number of my friends were players. There had been an earlier game whose title I leave as an exercise to the reader. The game was run using Australian Tax Office mainframes in downtime. It was conceptually kind of a gigantic interstellar conquest run using Traveller's "High Guard" combat rules, and it allowed players to operate as corporations, spies, or straight out interstellar empires.

My point: the experiment has been run before.

Start building it now.

That's the only answer. Get off your butt, stop taking in more feedback and other excuses for you to actually do something, and start building the prototype now. There are always reasons for you to wait, gather more data and feedback, etc, but all that will do is stall you and make you lose momentum. Start coding now, and don't worry about what you do or do not know, just do it.
Math is not the ultimate fabric of the universe. Mathematics is a set of formal languages and concepts that can be used to describe the nature of reality really well. Those laws and phenomena that can be described using math are the "fabric of reality". A language is not equivalent to the things expressed with it.

The frequent invocations and interweavings of human concepts such as consciousness into this muddled mess of an explanatory video serve little purpose beyond giving the whole thing a vague New Age vibe that isn't really warranted and the whole thing could have been avoided by not intentionally mixing Math [the human construct] and Things-Described-By-Math [the inner workings of the universe].

Or, we could take lots and lots of not very rich people giving a little of their wealth. The last time that society relied on patronage for producing art, we didn't have around a platform that can potentially connect all humans to support the same artistic endeavor.

This is basically how blockbusters are financed nowadays, so it's a viable proposition. There's no evidence that changing from copyright to patronage would change that outcome.
> The blackjack games most casinos spread don't allow for a positive expectation, even when counting cards

It's true that terrible games have been proliferating lately (eg, 6:5 payoffs replacing 3:2), but can you really back up the claim that most casinos don't have a positive expectation (with counting) blackjack game? Do you just mean that to make it a positive expectation game you would need to use such a wide bet spread as to make the card-counting obvious? (Even then, I'm suspicious; Nevada is full of countable games. And are you ignoring strategy variation?)

It actually doesn't have to work at every casino; it would suffice if it worked at the casinos that had a good game - and a good glasses app could tell you which games were good. So yes, the glasses would have to be banned at the table.

As you'd expect. They covered his bail, and it's payable if he flees, which he did.

It's not an equality relationship. If it was an equality relationship it would be transitive. But as your parent points out, you have n=O(n^2), n^2=O(n^2) but not n=n^2, so transitivity doesn't hold.

Another way to see that the relationship can't be equality: the left hand side is a function, the right hand side is a set of functions. Two things from different classes can't be equal.

The relationship is simply set membership.
Thanks! I've tried to keep the feature set simple so maybe they are imagining it having things it doesn't.

I need to start taking more detailed feedback from people but I don't want to sway them by asking leading questions.

Even though it only has a primarly and secondary features, it's certainly still beyond what I've ever built before.

I'm considering all angles really. Even if it means selling the idea on, I'd rather it get built properly.
Probably wouldn't have amounted to much, though. If Signetics had patented it, purchasing it from him, he would have gotten what, maybe a few hundred dollars? That's about what most engineers receive for their patents from the employing company.

Now, if he had left Signetics and founded another company to create the 555, then he might have been rolling in dough.
